A newly discovered malware campaign has been found to target private users, retailers, and service businesses mainly located in Russia to deliver NetSupport RAT and BurnsRAT. The campaign, dubbed Horns&Hooves by Kaspersky, has hit more than 1,000 victims since it began around March 2023. The end goal of these attacks is to leverage the access afforded by these trojans to install stealer malware such as Rhadamanthys and Meduza . "Recent months have seen a surge in mailings with lookalike email attachments in the form of a ZIP archive containing JScript scripts," security researcher Artem Ushkov said in a Monday analysis. "The script files [are] disguised as requests and bids from potential customers or partners." The threat actors behind the operations have demonstrated their active development of the JavaScript payload, making significant changes during the course of the campaign. In some instances, the ZIP archive has been found to contain other docum...

Cybersecurity researchers have flagged a new ransomware family called Ymir that was deployed in an attack two days after systems were compromised by a stealer malware called RustyStealer. "Ymir ransomware introduces a unique combination of technical features and tactics that enhance its effectiveness," Russian cybersecurity vendor Kaspersky said . "Threat actors leveraged an unconventional blend of memory management functions – malloc, memmove, and memcmp – to execute malicious code directly in the memory. This approach deviates from the typical sequential execution flow seen in widespread ransomware types, enhancing its stealth capabilities." Kaspersky said it observed the ransomware used in a cyber attack targeting an unnamed organization in Colombia, with the threat actors previously delivering the RustyStealer malware to gather corporate credentials. It's believed that the stolen credentials were used to gain unauthorized access to the company's n...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Russian government agencies and industrial entities are the target of an ongoing activity cluster dubbed Awaken Likho . "The attackers now prefer using the agent for the legitimate MeshCentral platform instead of the UltraVNC module, which they had previously used to gain remote access to systems," Kaspersky said , detailing a new campaign that began in June 2024 and continued at least until August. The Russian cybersecurity company said the campaign primarily targeted Russian government agencies, their contractors, and industrial enterprises. Awaken Likho, also tracked as Core Werewolf and PseudoGamaredon, was first documented by BI.ZONE in June 2023 in connection with cyber attacks directed against defense and critical infrastructure sectors. The group is believed to be active since at least August 2021. The spear-phishing attacks involve distributing malicious executables disguised as Microsoft Word or PDF documents by assigning them double extensions like "doc...

Altered versions of legitimate Android apps associated with Spotify, WhatsApp, and Minecraft have been used to deliver a new version of a known malware loader called Necro. Kaspersky said some of the malicious apps have also been found on the Google Play Store. They have been cumulatively downloaded 11 million times. They include - Wuta Camera - Nice Shot Always (com.benqu.wuta) - 10+ million downloads Max Browser-Private & Security (com.max.browser) - 1+ million downloads As of writing, Max Browser is no longer available for download from the Play Store. Wuta Camera, on the other hand, has been updated (version 6.3.7.138) to remove the malware. The latest version of the app, 6.3.8.148, was released on September 8, 2024. It's currently not clear how both the apps were compromised with the malware in the first place, although it's believed that a rogue software developer kit (SDK) for integrating advertising capabilities is the culprit. Necro (not to be confused w...

Unnamed government entities in the Middle East and Malaysia are the target of a persistent cyber campaign orchestrated by a threat actor known as Tropic Trooper since June 2023. "Sighting this group's [Tactics, Techniques, and Procedures] in critical governmental entities in the Middle East, particularly those related to human rights studies, marks a new strategic move for them," Kaspersky security researcher Sherif Magdy said . The Russian cybersecurity vendor said it detected the activity in June 2024 upon discovering a new version of the China Chopper web Shell, a tool shared by many Chinese-speaking threat actors for remote access to compromised servers, on a public web server hosting an open-source content management system (CMS) called Umbraco. The attack chain is designed to deliver a malware implant named Crowdoor , a variant of the SparrowDoor backdoor documented by ESET back in September 2021. The efforts were ultimately unsuccessful. Tropic Trooper, also...

A previously undocumented advanced persistent threat (APT) group dubbed CloudSorcerer has been observed targeting Russian government entities by leveraging cloud services for command-and-control (C2) and data exfiltration. Cybersecurity firm Kaspersky, which discovered the activity in May 2024, said the tradecraft adopted by the threat actor bears similarities with that of CloudWizard , but pointed out the differences in the malware source code. The attacks wield an innovative data-gathering program and a slew of evasion tactics for covering its tracks. "It's a sophisticated cyber espionage tool used for stealth monitoring, data collection, and exfiltration via Microsoft Graph, Yandex Cloud, and Dropbox cloud infrastructure," the Russian security vendor said . "The malware leverages cloud resources as its command and control (C2) servers, accessing them through APIs using authentication tokens. Additionally, CloudSorcerer uses GitHub as its initial C2 server....

Cybersecurity researchers have disclosed multiple security flaws in Cinterion cellular modems that could be potentially exploited by threat actors to access sensitive information and achieve code execution. "These vulnerabilities include critical flaws that permit remote code execution and unauthorized privilege escalation, posing substantial risks to integral communication networks and IoT devices foundational to industrial, healthcare, automotive, financial and telecommunications sectors," Kaspersky  said . Cinterion modems were originally developed by Gemalto before the business was  acquired  by Telit from Thales as part of a deal announced in July 2022. The findings were  presented  at the OffensiveCon held in Berlin on May 11. The list of eight flaws is as follows - CVE-2023-47610  (CVSS score: 8.1) - A buffer overflow vulnerability that could allow a remote unauthenticated attacker to execute arbitrary code on the targeted system by ...

The U.S. Department of State on Monday said it's taking steps to impose visa restrictions on 13 individuals who are allegedly involved in the development and sale of  commercial spyware  or who are immediately family members of those involved in such businesses. "These individuals have facilitated or derived financial benefit from the misuse of this technology, which has targeted journalists, academics, human rights defenders, dissidents and other perceived critics, and U.S. Government personnel," the department  said . The names of those subjected to visa restrictions were not disclosed, but the move comes more than two months after the U.S. government said it's  enacting a new policy  that enforces visa constraints on people engaging in practices that could threaten privacy and freedom of expression. It also aims to counter the misuse and proliferation of commercial spyware that has been put to use by authoritarian gover...

Government entities in the Middle East have been targeted as part of a previously undocumented campaign to deliver a new backdoor dubbed CR4T. Russian cybersecurity company Kaspersky said it discovered the activity in February 2024, with evidence suggesting that it may have been active since at least a year prior. The campaign has been codenamed  DuneQuixote . "The group behind the campaign took steps to prevent collection and analysis of its implants and implemented practical and well-designed evasion methods both in network communications and in the malware code," Kaspersky  said . The starting point of the attack is a dropper, which comes in two variants -- a regular dropper that's either implemented as an executable or a DLL file and a tampered installer file for a legitimate tool named  Total Commander . Regardless of the method used, the primary function of the dropper is to extract an embed...

Cybersecurity researchers have discovered a new Raspberry Robin campaign wave that has been propagating the malware through malicious Windows Script Files ( WSFs ) since March 2024. "Historically, Raspberry Robin was known to spread through removable media like USB drives, but over time its distributors have experimented with other initial infection vectors," HP Wolf Security researcher Patrick Schläpfer  said  in a report shared with The Hacker News. Raspberry Robin, also called QNAP worm, was  first spotted  in September 2021 that has since  evolved into a downloader  for various other payloads in recent years, such as SocGholish, Cobalt Strike, IcedID, BumbleBee, and TrueBot, and also serving as a precursor for ransomware. While the malware was initially distributed by means of USB devices containing LNK files that retrieved the payload from a compromised QNAP device, it has since  adopted other methods  such as social engineering and malv...

A Linux version of a multi-platform backdoor called  DinodasRAT  has been detected in the wild targeting China, Taiwan, Turkey, and Uzbekistan,  new findings  from Kaspersky reveal. DinodasRAT, also known as XDealer, is a C++-based malware that offers the ability to harvest a wide range of sensitive data from compromised hosts. In October 2023, Slovak cybersecurity firm ESET  revealed  that a governmental entity in Guyana had been targeted as part of a cyber espionage campaign dubbed Operation Jacana to deploy the Windows version of the implant. Then last week, Trend Micro  detailed  a threat activity cluster it tracks as Earth Krahang and which has shifted to using DinodasRAT since 2023 in its attacks aimed at several government entities worldwide. The use of DinodasRAT has been attributed to various China-nexus threat actors, including  LuoYu , once again reflecting the tool sharing prevalent among hacking crews identified as acting o...

Chinese users looking for legitimate software such as Notepad++ and VNote on search engines like Baidu are being targeted with malicious ads and bogus links to distribute trojanized versions of the software and ultimately deploy  Geacon , a Golang-based implementation of Cobalt Strike. "The malicious site found in the notepad++ search is distributed through an advertisement block," Kaspersky researcher Sergey Puzan  said . "Opening it, an attentive user will immediately notice an amusing inconsistency: the website address contains the line vnote, the title offers a download of Notepad‐‐ (an analog of Notepad++, also distributed as open-source software), while the image proudly shows Notepad++. In fact, the packages downloaded from here contain Notepad‐‐." The website, named vnote.fuwenkeji[.]cn, contains download links to Windows, Linux, and macOS versions of the software, with the link to the Windows variant pointing to the official  Gitee repository  containin...

Cracked software have been observed infecting Apple macOS users with a previously undocumented stealer malware capable of harvesting system information and cryptocurrency wallet data. Kaspersky, which identified the artifacts in the wild,  said  they are designed to target machines running macOS Ventura 13.6 and later, indicating the malware's ability to infect Macs on both Intel and Apple silicon processor architectures. The attack chains leverage booby-trapped disk image (DMG) files that include a program named "Activator" and a pirated version of legitimate software such as xScope. Users who end up opening the DMG files are urged to move both files to the Applications folder and run the Activator component to apply a supposed patch and run the xScope app. Launching Activator, however, displays a prompt asking the victim to enter the system administrator password, thereby allowing it to execute a Mach-O binary with elevated permissions in order to launch the modif...

The  Operation Triangulation  spyware attacks targeting Apple iOS devices leveraged never-before-seen exploits that made it possible to even bypass pivotal hardware-based security protections erected by the company. Russian cybersecurity firm Kaspersky, which  discovered  the  campaign  at the beginning of 2023 after becoming one of the targets,  described  it as the "most sophisticated attack chain" it has ever observed to date. The campaign is believed to have been active since 2019. Operation Triangulation gets its name from the use of a fingerprinting technique called canvas fingerprinting to draw a yellow triangle on a pink background with Web Graphics Library ( WebGL ) in the device's memory. The exploitation activity involved the use of four zero-day flaws that were fashioned into a chain to obtain an unprecedented level of access and backdoor target devices running iOS versions up to iOS 16.2 with the ultimate goal of gathering ...

The threat actor referred to as  Cloud Atlas  has been linked to a set of spear-phishing attacks on Russian enterprises. Targets included a Russian agro-industrial enterprise and a state-owned research company, according to a  report  from F.A.C.C.T., a standalone cybersecurity company formed after Group-IB's formal exit from Russia earlier this year. Cloud Atlas, active since at least 2014, is a cyber espionage group of unknown origin. Also called Clean Ursa, Inception, Oxygen, and Red October, the threat actor is known for its persistent campaigns targeting Russia, Belarus, Azerbaijan, Turkey, and Slovenia. In December 2022, Check Point and Positive Technologies  detailed  multi-stage attack sequences that led to the deployment of a PowerShell-based backdoor referred to as PowerShower as well as DLL payloads capable of communicating with an actor-controlled server. The starting point is a phishing message bearing a lure document that exploits  ...

Unauthorized websites distributing trojanized versions of cracked software have been found to infect Apple macOS users with a new  Trojan-Proxy  malware. "Attackers can use this type of malware to gain money by building a proxy server network or to perform criminal acts on behalf of the victim: to launch attacks on websites, companies and individuals, buy guns, drugs, and other illicit goods," Kaspersky security researcher Sergey Puzan  said . The Russian cybersecurity firm said it found evidence indicating that the malware is a cross-platform threat, owing to artifacts unearthed for Windows and Android that piggybacked on pirated tools. The macOS variants propagate under the guise of legitimate multimedia, image editing, data recovery, and productivity tools. This suggests that users searching for pirated software are the targets of the campaign. Unlike their genuine, unaltered counterparts, which are offered as disk image (.DMG) files, the rogue versions are deliv...

An unspecified government entity in Afghanistan was targeted by a previously undocumented web shell called  HrServ  in what's suspected to be an advanced persistent threat (APT) attack. The web shell, a dynamic-link library (DLL) named "hrserv.dll," exhibits "sophisticated features such as custom encoding methods for client communication and in-memory execution," Kaspersky security researcher Mert Degirmenci  said  in an analysis published this week. The Russian cybersecurity firm said it identified variants of the malware dating all the way back to early 2021 based on the compilation timestamps of these artifacts. Web shells are typically  malicious tools  that provide remote control over a compromised server. Once uploaded, it allows threat actors to carry out a range of post-exploitation activities, including data theft, server monitoring, and lateral advancement within the network. The attack chain involves the  PAExec  remote administra...
